A comathematician is a machine for turning cotheorems into ffee.

For nostalgia I still keep the scanned images of the old herbarium I had to make in my biology class ten years ago.

The scanner still works, and it is still in use. A Canon Lide 30. The old computer is broken, unfortunately. The herbarium is still somewhere in my closet.

Nostalgia ...
